But the fire that followed burned up hundreds of millions of dollars’ worth of buildings and homes. Never before in history has a city been so completely destroyed. San Francisco is gone. The factories, the great stores and newspaper buildings, the hotels, and the great houses of the rich are all gone. ②On Wednesday morning at a quarter past five came the earthquake. A moment later, the disaster was a fact. South of Market Street, in the working-class neighborhoods and in the factories, fires started. Within an hour of the first quake, the smoke could be seen 100 miles away. The sun was red in the dark sky. There was no stopping the fires. The firefighters to whom the task was given did their best but there was no way to organise or communicate. The railway tracks were now useless and there was no water in water pipes. All of the ways man had made to keep the city safe were gone in the 30 seconds the earth moved. ③By Wednesday afternoon, half the heart of the city was gone. At that time, I watched the disaster from a ship on the bay（ 海湾）. Out at sea it was calm. No wind came up. Yet, from every direction- east, west, north, and south- strong winds blew upon the unlucky city and those whose homes had once stood in its green hills.
